Why is it important to avoid compacting soil around a mound system?

Avoiding compaction of soil around a mound system is crucial for the proper functioning of the system. Compacted soil can restrict water flow, which is essential for the effective treatment of wastewater in a soil absorption system. When the soil becomes compacted, it reduces the pore spaces that allow water to move through and be absorbed by the soil. This can lead to inadequate drainage and potentially result in system failure, as the wastewater cannot be adequately treated and may surface, causing odor issues or environmental contamination.

In contrast, maintaining loose, well-aerated soil around the mound allows for better infiltration and interaction between the soil and the wastewater, facilitating the necessary biological processes that break down pollutants. Proper water flow also ensures that the system operates efficiently and extends its longevity. Thus, the significant impact of soil compaction on water movement and system performance underscores why avoiding compaction is critical.
